If you purchase them separately, then you must use TWO transceiver keys. Your cheapest option if you prefer separate units, is to purchase a PCI USB 2.0 card which will give you an extra 5 (usually) USB ports.
Wireless Keyboard & Mouse bought separately, can they share the USB key

I have bought a MS wireless mouse 4000 and am wondering if i can buy the keyboard separately and have them use the same USB key. I only have 3 USB slots, and don't want 2 of them occupied by a mouse & keyboard. Do i need to buy the keyboard & mouse as a single unit? or can i mix & match ? Thanks,
